Application filed March 29,1928, Serial No. 265,703, and in Germany April 4, 1927.

This invention relates to a cold box or refrigerating box having a removable ice container combined with the vessel for the melted water and in a metallic conducting connection therewith. Devices of this type are well known and the present invention red sides in the provisionin the water vessel The invention is illustrated in the accompanying drawing, Fig. lbeing a cross sec-' tion through the cold box and Fig. 2 a section on a larger scale of the ice container.

The cold box a is accessible in known manner from above. Covers (1 and e are provided for the ice container or casing b and the storage chamber 0 respectively. The ice container b and the vessel f for the melted water are formed by a single box consisting of four walls and a bottom. A partition 9 made ofcorrugated sheet metal is arranged 5 in the upper art of this box with a slight inclination re atively to the outer wall it. Close to the lateral wall the partition 9 is provided in the depressions between the corrugations with a series of holes 11 throu h which the melted water runs away into t e vessel 7 located below. A wide openin Z which renders the water chamber f accessi le and allows bottles m and the like to be .placed thereinor removed therefrom is pro dicated by arrows in Fig. 1 the air isfable to move through the holes .3 alongthe outer side wall and below the melted water in the cold space 0 proper wherethe cooled air iswarmed gradually by provisions or. the like on the shelves t and u of the storage cham: her 0. It then rises and passes either through air outlets (not shown) in the cover e into the open air or back through the higher openings 8 in the other wall of the ice box. to the ice block b. 0 indicates. a vessel for catching overflowing melted water.

What I claim is:

1. An ice unit for refrigerators comprising a casing having a plurality of feet on the bottom thereof to maintain it in spaced relation in the refrigerator; 3, metal partition in said casing at approximately the mid portion thereof to divide the casing into uper and lower sections the u er section of the casing being adapted to receive ice and having openings in the walls thereof to permit circulation of air, and the slower sectionbeing adapted to receive the water from the melting ice to form a cooling vessel for bottles and the like andthe wall of the casing of the lower section having an opening therein above the water level to receive the bottles; and means for permitting the escape of the water from the lower section and at thesame time to maintain the water at any desired level.

. 2. An ice unit for refrigerators comprising a casing adapted to be placed in the refrigerator in spaced relation from the walls thereof and having a plurality of feet on the bottom thereof to maintain it in spaced relation from the bottom of the refrigerator; a corrugated metal partition in said casing at approximately the mid portion thereof to divide 'the casinginto upper and lower sections and having holes-therein to permit the escape of water, the upper section of the casing being adapted to receive ice and having openings in the walls thereof to permit the circulation of air, and the lower section being adapted to receive the'water from the upper section from the melting ice to form a cooling vessel for bottles and the like and the wall of the casing of the lower section having an opening therein above the water level to receive the bottles; and a pipe having an air seal therein extending through the bottomof the casing and into the lower :sect io'nfto permit the-escape of the water therefrom and at the same time to maintain the water'at any desired level.

In testimony whereof I have afiixed my signature.
